Storm sash



United States Patent 3,080,622 STORM SASI-I Bernard E. Mendelsohu,Newton, Mass. (7 Livingstone Sh, Dorehester, Mass.) Filed Jan. 23, 1961,Ser. No. 84,416 8 Claims. (CI. 2055) This invention relates to stormwindows and more particularly comprises an improvement upon the stormwindow sash disclosed in my co-pending application Serial No. 20,770,filed April 7, 1960, and entitled Storm Window. This application is acontinuation-in-part of that earlier application.

In my earlier application, supra, I disclosed a multisash tilt-typestorm window wherein each of the several sashes carries extendableflanges in the side members, which when extended lie within channelsformed in the window frame. The flanges carried on the side members ofthe sashes extend substantially throughout the full height of the sashesand are moved by means of actuators attached to the extreme ends of theflanges. The actuators disposed at the top of the sashes and secured tothe upper ends of the flanges are friction loaded so that the upperparts of the flanges remain in the position chosen by the operator.However, the actuators at the bottoms of the sashes secured to the lowerends of the flanges are spring loaded to urge the flanges outwardlybeyond the sides of the sashes and into the channels of the windowframe.

The features of the earlier invention outlined above are allincorporated into the sash of the present invention. However, the stormsash of the present invention includes additional features which aid inits assembly and generally enhance the strength of the sash.

My invention will be better understood and appreciated from thefollowing detailed description of the preferred embodiment thereof, readin connection with the accompanying drawings in which:

FIGURE 1 is a fragmentary front elevation view of a sash constructed inaccordance with my invention;

FIGURE 2 is a fragmentary side elevation of the sash shown in FIGURE 1;

FIGURE 3 is an enlarged fragmentary perspective view, partly in section,showing a portion of the sash of FIGURE 1;

FIGURE 4 is a cross-sectional elevation view of a portion of the sashshown in FIGURE 1;

FIGURE 5 is a view similar to FIGURE 4 but showing an alternate positionfor part of the mechanism;

FIGURE 6 is a cross-sectional view taken along the corresponding sectionline in FIGURE 3;

FIGURE 7 is an exploded elevation view of a portion of the sash shown inFIGURE 1; and

FIGURE 8 is a cross-sectional view taken along the corresponding sectionline in FIGURE 7.

The embodiment of the storm sash shown in the drawings includes in itsgeneral organization a sash frame 10 having a side member 12, a topmember 14, a bottom member 16 and glass 13. It will be appreciated thata second side member identical to side member 12 shown in FIGURE 1extends parallel to the side member 12 on member 24. This H-shapedcross-sectional configuration defines a pair of channels 26 and 28disposed back to back and opening in opposite directions. The channelsare generally vertically oriented and extend from the top member 14 tothe bottom member 16. A secondary channel 30 is formed within thegeneral confines of the channel 28 and is defined by sides 32 and 34 andpanel 36. The secondary channel 30 extends throughout the full length ofthe side member 12 and contains a length of weather stripping assuggested at 38. The weather stripping 38 is so positioned that it bearsagainst the supporting or bearing surface on the storm Window frame (notshown) when the sash is mounted in the frame. This feature of myinvention is disclosed in detail in my co-pending application Serial No.20,770, supra, and does not form part of this invention.

The top member 14 and the bottom member 16 join the top and bottom ofthe side member 12 at mitered corners as suggested at 40 and 42 inFIGURE 1. The bottom member '16 and the top member 14 are virtuallyidentical to the similar members of the sash shown in my earlierco-pending application, supra. The top and bottom members each include achannel identified respectively by numerals 44 and 46, that formcontinuations of the channel 28 of the side member 12 when the threeparts are assembled together. The channels 44 and 46 open inwardly ofthe sash 10, that is, face the inside of the dwelling upon which thestorm window is mounted.

Corner brackets 48 and 50 are employed to join the top member 14 withthe side member 12 and the bottom member 16 with the side member 12,respectively. The corner bracket 50 is shown in cross-section in FIGURES'4 to 6 and is shown partly broken away in FIGURE 3. The bracket 56includes a horizontal arm 52 disposed in the channel 46 of the bottommember 16 and a Vertical arm 54 disposed in the channel 23 of the sidemember 12. The horizontal arm 52 is composed of a face plate 56 and apair of horizontally disposed and spaced apart flanges 58 and 60 whichbear against the sides of the channel 46 in the bottom member 16. Theface plate 56, the flanges 53 and 60, and the base of the channel 46cooperate to define an enclosed track within which is mounted a latch 62described in detail below. The vertical arm 54 of the bracket 50includes a face plate 64 which bears against the inner surface of theside 22 of the side member 12 and a flange 66 disposed against the baseof the channel 28 as defined by the web 24. It will be notedparticularly in FIGURE 6 that the flange 66 and the plate 64 fit snuglywithin the channel 28. In FIGURES 3 and 6 it will also be noted that alip 68 is formed as an integral part of the side 22 of side member 12and is provided with an undercut inner surface 79 that engages a matingsurface 72 formed on the end of the face plate 64 of the vertical arm54. The undercut surface it? of the lip 68 cooperates with the generalcharacter of the fit of the vertical arm 54 in the channel 23 to holdthe vertical arm firmly in place. It also provides specific resistanceagainst displacement of the vertical arm 54 in the channel 28 when thevertical arm is staked in place as suggested at '74.

The horizontal and vertical arms 52 and 54 of the bracket 50 areapproximately one inch in length and it is essential that in therelatively short distance provided a firm connection be made between thebracket arms and the bottom and side members of the sash. It is to benoted that the corner bracket 43 which serves to interor track formed inthe Window frame (not shown) to enhance the weather tightness of thestorm window. As I described in detail in my earlier co-pendin-gapplication, supra, the retract-able nature of the flange 80 permits thesash to be assembled readily as a tilt-type window within the frame butyet provides the full protection of the track-type windows of the priorart. That is, because the flange 86 may be withdrawn wholly within theconfines of the channel 28 in the side member 12, the sash may be tiltedinwardly when the flange is so withdrawn, to facilitate cleaning andremoval, but when the sash is mounted in the frame and the flangeextends into the track or channel of the frame it forms a weather-tightseal along the sides of the sash. In FIG. 6 flange 80 is shown spacedfrom members 36 and 64. In actuality flange 80 has a tighter fit withthese members than actually shown.

The flange 80 extends substantially coextensive with the side member 12to provide the benefits of a tight connection with the frame throughsubstantially the full height of the sash. The flange includes a mainplate or panel 82 oriented parallel to the sides 20 and 22 of the sidemember 12 and a rib 84- forming a continuation of the panel 82 at itsinner edge and disposed parallel with the web 24 of the side member. Itwill be noted in FIG- URE 7 that the rib 84 is not coextensive with thepanel 82 but rather terminates short of its ends as suggested at 86 and88. The inner edge of the panel 82 represented by line 89 in FIGURES 7and 8 terminates a short distance from the web 24 of the side member 12to form a gap between the panel and web. The rib 84 throughout the majorportion of the flange 80 fills that gap so that the rib 84 actuallycontacts the web 24 when the flange is withdrawn within the channel 28.To facilitate complete withdrawal of the flange 80 into the channel 28it is necessary to eliminate from the ends of the flange 80 the rib 84as the plate 66 of the vertical arm 54 of the bracket 50 is disposed inthe area which would otherwise be occupied by the end of the rib 84.Thus, the rib 84 is in effect cut away at the ends of the flange toprovide room for the portion of each corner bracket which lies againstthe web 24 at the ends of the side member 12.

Earlier I referred to latch 62 slidable within the enclosed trackdefined by the horizontal arm 52 of bracket 50 and the base of channel46 in the bottom member 16. The latch 62 includes an enlarged head 90which rides along the side of the window frame in which the sash ismounted and may cooperate with stops formed on the inside of the frameto retain the sash in an open position. It will be noted that the latchcarries an upwardly extending tongue 92 just rearwardly or inwardly ofthe head 90, that engages a slot 94 cut in the bottom of the panel 82 ofthe flange 80 to support the flange in the channel 28 of the side member12. The tongue 92 has an enlarged base in the form of a shoulder 96 thatserves to space the tongue 92 from the plate 66 of the vertical arm 54of the bracket 50. Thus, as is shown in FIGURE 4, the tongue 92 isspaced from the plate 66 a distance which is adequate to receive thetine 98 forming one side of the slot 94 in flange 80. A similararrangement is used to support the upper end of the flange 80. It willbe noted in FIGURE 7 that a slot 100 is provided at the upper end of theplate 82 of the flange 80 to receive a tongue carried by the latch 102disposed in the track formed by the horizontal arm of the bracket 48 andthe base of the channel 44 in the top member 14.

The shoulder 96 serves as a guide or gauge to facilitate the assembly ofthe sash frame. When the bottom member 16 is secured to the side member12 by means of the bracket 50 and the latch 62 is disposed in theposition shown in FIGURES 3 and 4, the shoulder 96 spaces the tongue 92from the inner surface of the plate 66 of the vertical arm of thebracket and the flange 80 may he slipped into the channel 28 formed inthe side member. By running the flange 80 against the web 24 the tine 98falls in place behind the tongue 92. Thus, what otherwise could be aproblem in assembling the window is avoided. Similarly, when the topmember 14 is connected to the side member 12 the tongue on the latch 102will automatically align itself with the slot 100 at the top of theflange and slip into place.

The configuration of the flange 80, namely, the presence of the rib 84normal to the panel 82 which makes up the major portion of the body ofthe flange provides a guide to prevent the floating flange fromdistorting or wobbling. The rib 84 bears against the inner surface ofthe side 22 of the side member while the ends of the panel 82 ride onthe face plates of the vertical arms of the top and bottom brackets 48and 50. Throughout the length of the flange 80, the panel 82 is alsoguided between the lip 68' formed on the outer end of the side 22 andthe inner face of the panel 36 which defines in part the secondarychannel 30. The rib 84 formed as a bend in the panel 82 also adds agreat deal of stiffness to the flange to prevent twisting.

From the foregoing description it will be appreciated that numerousmodifications may be made of my invention without departing from itsspirit. Therefore, I do not intend to limit the breadth of my inventionto the single embodiment illustrated and described. Rather, it is myintention that the scope of this invention be determined by the appendedclaims and their equivalents.
